Inhaler Technique: Simple Steps for Better Breathing
If you rely on an inhaler, the way you use it can be the difference between a quick relief and a wasted dose. Many people think just pressing the can is enough, but the lungs only get the medicine when the technique is right. Below you’ll find a clear, practical walk‑through that works for most metered‑dose inhalers (MDIs) and dry‑powder inhalers (DPIs).
Why the Right Technique Matters
When you miss a breath or forget to shake the inhaler, the medication stays in the device instead of reaching the airways. That means you could feel more shortness of breath, need another puff, and waste medicine that costs a lot. Good technique also lowers the risk of side effects such as sore throat or hoarse voice, because less spray lands in the mouth and throat.
How to Use a Metered‑Dose Inhaler (MDI)
1. Shake it well. Give the inhaler a good shake for about 5 seconds to mix the medication evenly.
2. Exhale fully. Breathe out completely, but don’t puff out through your mouth – just let the air go out gently through your nose.
3. Seal your lips. Place the mouthpiece between your teeth and close your lips around it.
4. Press and inhale. As you start a slow, steady breath in, press the canister once. Keep breathing in for 3–5 seconds.
5. Hold your breath. Once the inhaler is empty, hold the breath for about 10 seconds to let the medicine settle.
6. Exhale slowly. Breathe out gently, preferably through the nose, and wait at least 30 seconds before a second puff if needed.
How to Use a Dry‑Powder Inhaler (DPI)
DPIs don’t need shaking, but you must inhale quickly to pull the powder into your lungs. 1. Load the dose. Follow the device’s instructions – usually a click or twist that readies a dose. 2. Exhale away from the inhaler. Blow out fully, keeping the inhaler open, so you don’t blow the powder away. 3. Seal your lips and inhale fast. Place the mouthpiece in your mouth, close your lips, and take a rapid, deep breath in. 4. Hold for a moment. Pause for 2–3 seconds, then exhale slowly. 5. Check the dose. Some DPIs have a dose counter; make sure it moved.
Both types of inhalers benefit from a spacer or a holding chamber. A spacer catches the spray, giving you more time to inhale and reducing mouth‑throat deposits.
Practice makes perfect. Try the steps a few times without medication, then with a placebo inhaler, before you need relief during an attack. If you’re still unsure, ask your pharmacist or doctor for a quick demo – they can watch you and fix any mistakes on the spot.
Remember, consistent use of the right technique means better symptom control, fewer flare‑ups, and possibly lower overall medication costs. Keep this guide handy in your bathroom or on your phone, and you’ll be ready the next time you reach for your inhaler.
